Broken Sword: The Shadow of the Templars (2D) (My favourite)
Broken Sword II: The Smoking Mirror (2D) (Really good too, but shorter than the first)
Broken Sword: The Sleeping Dragon (3D) (Was decent but not as good as the others)
Broken Sword: The Angel of Death (3D) (Haven't played as it required a certain graphics card)

And then they did the 'director's cut'/remakes of the first two games, but I haven't played those versions. There's also a fan-made game called Broken Sword 2.5 (http://www.brokensword25.com/) which is good, 2D like the first two games.

Looks very interesting (I like the use of 3D rendered models on 2D backgrounds) but what is the "Special boxed version of the game only available to funders" about? If not enough money is raised it might not be made.
The voice acting sounds good

Played it a while back. Great throwback to the first games in the franchise. However, I felt they should've just made a complete game instead of dividing the story in two parts, the last part of which will be out later this year.
